Tips: Pneumatic actuated ball valve troubleshooting
Pneumatic ball valve has no feedback signal.
The signal line of the pneumatic ball valve consists of a pair of control signal lines and a pair of feedback signal lines. When the PLC gives a signal to the valve, the signal is converted in the positioner of the regulating valve, and the action of the valve stem is controlled by the air source pressure. The stroke of the valve stem transmits the opening of the valve through the feedback signal of the regulating valve.
If there is no feedback signal from the pneumatic ball valve, use a multimeter to check whether there is voltage at each contact. To check for proper wiring connections, check for damaged signal wires, and check for loose signal wires.
The valve cannot be closed to the zero position.
- It is actually closed to the zero position, but the feedback indication is not there. This is a signal problem, which can be solved by adjusting the positioner.
- It is actually not closed tightly, and the most likely cause is that the valve sealing gasket is damaged. Or the rotation of the valve stem connection is blocked, which requires dismantling the valve body during maintenance, and contacting the pneumatic ball valve manufacturer to replace the sealing gasket and add lubricating oil to the rotating part to make it work normally.
